New Famiclone from Dreamgear, who usually makes handheld pad type clones. Now however that Famiclones are "Legal" you can find these things on legit auction sites, el-cheapo stores like Walmart, etc.

Looks like they took a variant of the Dreamcast case, painted it blue, and made their own variant boomerang controllers. Games are hacks of NES games, mostly shooters and simple maze games.
